Abstract

PURPOSE: To obtain a silicone foam readily injectable into gaps, e.g. hole parts of electric wires, having improved heat resistance and high fireproof properties, by mixing two specific types of siloxane compositions, and forming a foam at room temperature.
CONSTITUTION: 100pts.wt. Mixture containing polydimethylsiloxane phenylmethylvinylsiloxane-terminated block polydimethylsiloxane, etc. is mixed with a platinum catalyst and further quartz powder and carbon, and adjusted to a viscosity of 4,000W10,000cps (20°C). 100pts.wt. Resultant mixture is then mixed with 5W 30pts.wt. aluminum silicate to give a composition (A). 100pts.wt. Mixture containing polydimethylsiloxane, polymethylhydrogensiloxane, etc. is adjusted to a viscosity of 4,000W10,000cps (20°C) with quartz powder and white inorganic pigment and mixed with 5W30pts.wt. zinc oxide to give a composition (B). The compositions (A) and (B) are mixed to form a foam at room temperature.
